JAD and RAD ~ Joint Application Development and Rapid Application Development ~ are IBM-developed methodologies for improved User acceptance of higher quality business solutions. Together they build on Software Engineering tools and group decision making techniques through the use of a trained JAD Facilitator. The methodologies have proven to be effective beyond software development to course development, product development, project management work breakdown structures and any effort that requires group consensus decisions. Several JAD-like agile software development techniques have evolved such as SCRUM and PRiSM. John Crosby was the IBM curriculum owner for JAD/RAD courses and extended the method adding business process and data modeling.
